Ink marking line · 1 roll

Inked lines are not very practical in modern cities, so the Observation Bureau has replaced "lines" with three more functional methods: sticking, wrapping, and hanging.

• Knot Pattern Diagrams: Three commonly used knotting methods, with step-by-step illustrations.
• Door and Corner Sealing Notes: Which four corners to start with, how long is enough, and when a restart is mandatory.
• Unraveling Reminders: Which end to start from when finishing—get this step wrong, and all previous work is wasted.

Suitable Identities

Grave robbers, funeral practitioners; clockmakers and forensic pathologists also use it for marking.
